Test for integer value
显示 更早的评论
I am trying to make a battleship styled game, one of the parts involve getting a set of user input 'firing coordinates', which I then need to test to make sure it is an integer value 1 through 10, what function can I use to test that it is an integer?
*edit: I am looking for a logical operator or else condition that can specify a non integer input.

See the following:
doc fix
doc ceil
doc floor
doc round
E.g., for a scalar x
if( round(x) == x )
% x is an integer

Perhaps no better no worse than James's solution just different
iswholenumber = mod(x,1)==0

according to my test slightly faster, but need to assume the smaller range of x of be working:
x == int32(x)
